When you see reporting like this it means there was some study that had some evidence of some effect that somewhat matches the description in the headline, but nothing more than that. How good of a study it was, how large the effect, how in alignment or not it is with a body of evidence, how reproduceable it is, how exaggerated the press release is. Are all left out and are all critical to how much anyone should care about the statement. What it definitely does not mean is "all scientists are asserting this truth in the headline"
